Main Page | See live article | Alphabetical index Pump action shotguns are a subclass of shotguns that are distinguished in the way in which spent shells are extracted and fresh ones are chambered. The weapon has a single barrel above a tube in which between 3 and 7 shells are inserted, depending on the model. New shells are loaded by pulling a pump handle attached to the cartridge tube toward the user, then pushing it back into place to insert the cartridge into the chamber. This action simultaneously projects the most recently fired shell out the side ejection port. The length of these shotguns are approximately 24in to 34in. This article is from Wikipedia.
